如何将Autocad文件转换为具有清晰视图的pdf文件？

Question

我正在研究一个将autocad文件.dwg转换为PDF的asp.net项目。

我使用以下代码进行操作：

using (var image = Aspose.CAD.Image.Load(filePath))
{
    // create an instance of CadRasterizationOptions & set resultant page size

    var rasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions()
    {
        PageSize = new Aspose.CAD.SizeF(image.Size.Width, image.Size.Height),
    };

    // save resultant PDF
    image.Save("****" + "***", new Aspose.CAD.ImageOptions.PdfOptions() { VectorRasterizationOptions = rasterizationOptions });
}

我得到的pdf文件：

我希望建筑物位于pdf文件的中心，并且足够大以对用户有用。我该如何解决这个问题并弄清楚呢？

Answer 1

我已观察到您共享的示例代码。您能否在导出的PDF中分享您遇到的问题。能否请您共享源DWG文件以及预期的输出PDF。同样，在您的上图中，当您在应用程序中设置Aspose.CAD的许可证时，左上角的水印也会被删除。

我正在Aspose中担任支持开发人员/宣传人员。

非常感谢

我建议您尝试使用下面的示例代码来设置渲染文件的打印区域。

        var cadImage =(CadImage) Aspose.CAD.Image.Load("filePath");

        CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
        rasterizationOptions.Layouts = new string[] { "Model" };
        rasterizationOptions.NoScaling = true;

        // note: preserving some empty borders around part of image is the responsibility of customer
        // top left point of region to draw
        Point topLeft = new Point(6156, 7053);
        double width = 3108;
        double height = 2489;

        CadVportTableObject newView = new CadVportTableObject();
        newView.Name = new CadStringParameter();
        newView.Name.Init("*Active");
        newView.CenterPoint.X = topLeft.X + width / 2f;
        newView.CenterPoint.Y = topLeft.Y - height / 2f;
        newView.ViewHeight.Value = height;
        newView.ViewAspectRatio.Value = width / height;

        for (int i = 0; i < cadImage.ViewPorts.Count; i++)
        {
            CadVportTableObject currentView = (CadVportTableObject)(cadImage.ViewPorts[i]);
            if (cadImage.ViewPorts.Count == 1 || string.Equals(currentView.Name.Value.ToLowerInvariant(), "*active"))
            {
                cadImage.ViewPorts[i] = newView;
                break;
            }
        }


        cadImage.Save("Saved.pdf", new Aspose.CAD.ImageOptions.PdfOptions() { VectorRasterizationOptions = rasterizationOptions });
